Are you guys serious? 2.0.6 was a _security_ bugfix release. If you continue to use 2.0.5 you expose your wordpress installation to well known and publicly available exploits. Every 13 year old script kiddie can deface your site when using PHP software with known security issues. This is irresponsible behavior.

If someone chooses to take a risk knowing that they'll take responsibility for the consequences then it's arguably not irresponsible. No one's going to get hurt but themselves if things go wrong. It's their choice.

Yeah, okay, that's right. But what if you run a big community blog where many users are registered. Then you have a responsibility for those users and their data (like private email addresses), too.
